SPECIFICATION forming part of Letters Patent title. 729,149, dated May 26;, 1&93. application filed March 28, 1908. Serial Lila. 150,033, (No modelil Machine for Making Artificial-Fuel Briquets,
of which the followingis a specification.
This invention relates to machines for making artificial-fuel briquets.
The object of the invention is a ready,sim-
ple, rapid, and thoroughly feasible and practical manner to compress divided 'combusti ble material, such as peat, into coherent form and to present it in such shape that in burning it will not disintegrate, but will retain its form and burn from the exterior after the manner of ordinary coal and similar fuel.
A further and important object of the invention is to provide a device of this character in which the compression is effected without the employment of a rigid resisting-body, as is the casein the machine shown and described in Letters Patent No. 723,150, granted to me on March 17, 1903, the necessary re-v sistance being afiorded by forcing the divided material through a tapering compression chamber of sufficient length to retain an appreciable quantity of compressed peat, which will afford a movable resistance to the material introduced at each operation of the compression mechanism.
A further object of the invention is to provide a device of this character in which pro-- vision is made for adjusting the area of the compression-chamber to thus alter the size of the resultant product and at the same time The gear is driven by a suitable train of gearincrease or decrease the resistance and alter to any desired extent the degree of compression of the material.
With theseand other objects in view the invention consists in the novel construction and arrangement of parts hereinafter de scribed,illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form, proportions, size, and minor details of the structure may be made without departing from the spirit or sacrificing any of the advantages of the invention. r
In the accompanying drawings, Figure 1 is a longitudinal sectional elevation of a mawheel 15.
chine characterized by the present invention. Fig, 2 is a plan view of one end of the machin'e, partly in section, on the line 2 2 of Fig. 1. Fig. '3 is a transverse sectional ele vation of a portion of the machine on the line 3 3 of Fig. 1. Fig. 4 is a detail sectional view,
on an enlarged scale, on the line 44 of Fig.
2, illustrating the construction and arrange-- ment of a portion of one of the-compression devices. Fig. 5 is a detail perspective view illustrating more particularly the construc tion and arrangement or the mechanism for adjusting the area of the compression chamher. Fig. 6 is a detail sectional view through the partition between two adjacent compres- I The machine forming the subject of the present invention is designedmore especially as an improvement in machines of that class employed for the compression of peat, where the material being treated must be subjected to extremely high pressure in order to obtain a product which will not disintegrate when handled or exposed. The operating mechanism employed is preferably similar to that illustrated and described in the hereinbeforementioned Letters Patent, to which reference is made for minor details which it has not been deemed necessary to illustrate in the present application.
1 designates a gearing wheel or wheels carried by a shaft 3, adapted to suitable bearings carried by the frame of the machine.
ing from a power-shaft 14, carrying a belt- 011 the gear-wheel is a wrist-pin 17, connected by a link 19 to a pair of levers 20 and 21, constituting thetoggle-joint. The lower terminal of theleverfli) is pivoted to an abutment 2i and the similar terminal of lever 21 is pivoted to a compression-plunger 526, thelatter being mounted for reciprocatory movement in a feed and compression chamber disposed below a suitable hopper 36, can ried by the frame and into which the material to be compressed is fed,'the plungerat each forward movement passing within the feed-chamber for a distance sufiicient to cut oil the-supply from the hopper, and thus act contracted compression chamber-4n other words, a tapering chamber-the inclined walls offering grad nally-increasing resistance to the passage of the material forced into the chamber by the plunger and the compression being in part effected by the gradually-contracted passage, thus reducing the cross-sectional area of the block of material, and in part by the resistance offered from previously-compressed charges remaining in the from end to end.
contracted compression-chamber, so that on emerging from the open discharge end of said chamber the material will be compressed to the desired extent and will be in the form of blocks or briquetmeach containing practically the same quantity and this quantity being regulated by the size of the feed-chamberand plunger and the extent of reciprocating movementoi said plunger. The blocks will at times adhere to each other, and mechanism is there fore provided for separating them as they issue from-the chamber. In the present case the feed-chamber and plunger are of suflicientsize tofeed four compression-chambers sim ultane oi isiy, these chambers, as illustrated in the drawings, having upper and lower-stationary walls 40 and opposite vertically-disposed adjustable walls 41, all of the walls being so arranged as to form in-each case a rectangular chamber of grad uallycontracted area The upper and lower walls of the chamber may be formed by suitable tapering plates rigidly secured to adjacent portions of the machine-frame, while the vertical walls are formed of comparatively,v thin sheets of metal ccnnected together at the feed-chamber end and forming at this point a sharp cutting edge which will readily divide the material and evenly distribute the same into the several com pression chambers. The plates 40013 two adjacent chambers gradnally diverge toward the discharge end and are continued out for some distance beyond the discharge end of the chambers, formed by the upper and lower plates, their extreme outer ends being supported in a suitable groove in a trausversely-disposed bar on or forming part of the frame of the machine and serving to hold the plates in proper position and to someextcnt resisting pressure due to the movement of the material by the plunger. I
in order to reduce the area of the compression-ciiainl ei's, and thus alter the size of the briquets and at the same time alter the degree of compression thereof, it being presumed that the quantity fed at each operation has been unchanged, I employ suitable mechanism for separating the adjacent walls of two chambers, such mechanism being more clearly shown in Figs. 2 and 5. The plates i strain of pressure. In order to hold the cut-' ting-points of the plates in proper relative position and to resist the end thrust of the plunger, the upper and lower edges of the forward ends of the plates are extended to form lugs 45, which are seated in suitable recesses in the upper and lower plates forming the top and bottom walls of the compressionchamber. Each plate is backed up bya wedgeshaped block 46, these being continued as far as possible toward the point of bifurcation of the two plates, and between these blocks is placed a longitudinally-adjustable wedge 47, which may be moved outwardly to in crease the size of the chambers or inwardly to decrease their area, as will be readily understood. The wedges 46 are of suflicient thickness to resist the compression strain without making it necessary to support them throughout their entire length, although it is of course preferable that the wedge 47'sh0uld be made as long as possible in order to provide a firm backing for the said blocks. As an adjusting means for the wedges 47 I employ screws 48, the threaded ends of which fit into correspondingly-threaded openings and the rear ends of the wedges. The oppositeends of the screws are unthreadedland extend through suitable guiding-openings in one of the transverse members of the frame and are provided at their outer ends with small gears 49, which intermesh to form a continuous line of gears, one of the screws or gears being provided with a crank-operating handle 50, so that all of the screws may be turned simultaneously to affect simultaneous adjustment of the wedges and by maintaining the compression-chambers of uniform size equalize the pressure throughout the width of the machine. I,
As the successive briquets emerge from the discharge end of the compression-chamber they detach themselves and fallby gravity; but in some cases, especially where compression is severe, the briquets willv be held together, and in order toinsure a positive discharge I employ a plurality of plunger-s 52,
adapted to make contact with the briquets' and detach the same. The several plungers 52, which separate the briquets, are carried by a bar 53, connected by two arms 54 to rods 55, extending through suitable guides on the frame and connected at their lower ends to a cross-bar 56, which is movable in one direction by a counterweight 57. Movement in the opposite direction to effect depression of the plungers is accomplished by the toggle mechanism 55, the operating lever 62 of which is provided with a toe 63, projecting into the path of movement of a block or cam 64, projecting from the lface of the gear-wheel 1. This mechanism effects downward movement of the plunger-s, while return movement to-the position shown inFi g. .l is accomplished by the counterweight 57. As the toggle mem* bers move to a substantially straight position,
-where the counterweight is ineffective, a lever 72 is employed to break the joint of the "toggles, said lever being pivoted at an inters mediate point to a bracket-70, depending from the bed of the machine, oneend of the lever having a slotted connection with the lever 62 and the opposite end thereof projecting into the path of movement of the rear end of the plunger, so that'as the latter is on the return stroke after each compression operation the toggle-joint will be broke and the counterweight allowed to act to returnthe'plungers to the elevated position.
In operation the hopper is supplied with the dividedniaterial, and at each movement of the plunger tothe position shown in Fig.
1 the feed chamber will be filled from said .hopper, the quantity entering the feed-chamber being practically the same at each movement. The plunger is then moved forward by the-toggle mechanism and forces the material from the feed-chamber into the compressionchambers, and the charge is' com-- pressed against the resistance olfered by a previously-compressed charge, as well as being subjected to transverse pressure by the continuously-contracted chambers. The compressedniaterial issues from the discharge end of the compression-chamber in the form of a continuous block, as. the successive charges may adhere to each other. The plungers then descend to separate the blocks.
The latter fall into a conveyer-trough 89, from which it is carried by a suitable endless.
; conveyor, a portion of which is illustrated at 90 in Fig. 1.'
Having thus described the invention, what is claimed is-- 1'.- In a machine for compressing material mm briqnets, a reciprocating plunger, 2, plurality of compression-chambers, plates form- -.ing the side walls of said chambers, separable backing-blocks disposed between the plates, a longitndinally-adjustable wedge between said blocks, and means for adjusting the wedge.
